煙霧報(bào)警器，又稱煙霧傳感器、火災(zāi)煙霧報(bào)警器、煙霧傳感器等?？偩€由總線供電，可連接到多個(gè)，與火警控制器連接，通信構(gòu)成報(bào)警系統(tǒng)，報(bào)警現(xiàn)場(chǎng)無(wú)聲音，主機(jī)有聲光提示，這種煙霧報(bào)警裝置一般稱為煙霧探測(cè)器。 </p> <p> 在報(bào)警器內(nèi)部有應(yīng)用到霍爾傳感器，在報(bào)警器中的霍爾傳感器起到了檢測(cè)自身電路的作用，當(dāng)火災(zāi)發(fā)生時(shí)煙霧報(bào)警器霍爾傳感器測(cè)量到市內(nèi)溫度達(dá)到一定點(diǎn)時(shí)，煙霧報(bào)警器就會(huì)亮燈并且開始運(yùn)作，一般可以用磁鐵來靠近煙霧報(bào)警器來進(jìn)行檢測(cè)，如果指示燈正常亮起這煙霧警報(bào)器一切正常，若沒亮起就必須要跟換新的報(bào)警器了。在煙霧報(bào)警器中常常會(huì)使用到全極霍爾傳感器。華芯精選各類霍爾元件,提供高質(zhì)量產(chǎn)品服務(wù),各類型號(hào)霍爾元件.霍爾元件一站搞定,價(jià)格優(yōu)惠歡迎咨詢!</p><div
